In the development of a dicot embryo, the suspensor chiefly functions to:

Answer: Push the embryo into the endosperm and aid nutrient uptake.

  • A Develop directly into the protective outer seed coat
  • B Form the future shoot apex
  • C Give rise to the radicle
  • D Push the embryo into the endosperm and aid nutrient uptake

Correct answer: D. Push the embryo into the endosperm and aid nutrient uptake

Explanation: The suspensor pushes the developing embryo deeper into the nutritive endosperm and serves as a conduit for nutrients to the embryo proper.

Double fertilization: pollen tube delivering two male gametes to the embryo sac, forming zygote and endosperm

Double fertilisation in angiosperms: one male gamete fuses with the egg to form the diploid zygote (syngamy), while the second fuses with the two polar nuclei to form the triploid primary endosperm nucleus (triple fusion). Image: Triploid, CC BY 3.0, via Wikimedia Commons.
